IN.4.5.1 The insulation resistance between the Tractive System and GLV System Ground will be measured.
IN.4.5.2 The available measurement voltages are 250 V and 500 V. All vehicles with a maximum nominal operation voltage below 500 V will be measured with the next available voltage level. All teams with a system voltage of 500 V or more will be measured with 500 V.
IN.4.5.3 To pass the Insulation Measurement Test the measured insulation resistance must be minimum 500 Ohm/Volt related to the maximum nominal Tractive System operation voltage.
